Report: Floyd Mayweather Bet $5.9 Million For Miami Heat To Beat Indiana Pacers in NBA Playoffs Game

According to new reports, WBC welterweight boxing champ Floyd Mayweather put a lot on the line with a recent bet on Monday's Game 7 of the NBA Eastern Conference Finals between the Miami Heat and Indiana Pacers-about $5.9 million worth.

As the New York Daily News reports, Mayweather, who has won WBC Super Featherweight and Light Welterweight titles along with several others, reportedly bet $5.9 million on Game 7 Monday between the Pacers and the Heat. Mayweather bet on the Heat to beat the Pacers, which they did in a 99-76 rout to seal Miami's third straight trip to the NBA Finals.

The story was originally broken by a tweet by Vegas Gambling Stream, the Twitter handle for gaming website Pregame.com .

"**ALERT** Good source from my #HeavyHitters Vegas crew alerted me that Floyd Mayweather has laid over $5,900,000 on Heat -7 tonight in Vegas," the tweet said.

One Las Vegas sports book director, speaking on the condition of anonymity, told Yahoo! News that he was doubtful that Mayweather had the ability to bet such a large sum on the game.

"I don't [think it's true]," the bookmaker said. "The only place that gave him sizeable wagers was Cantor [Gaming] and I've heard they cut many players way back. I don't think if he bet that at every book in town he could get that much, and we haven't taken anything here."

Mayweather, whose nickname is "Money," is known for getting some pretty big paydays, his most recent one being a six-year, $200 million deal with Showtime. However, as some gambling experts note, betting millions on a basketball game is not typical. The boxing superstar was the highest-paid athlete in the world last year, earning $85 million, according to Forbes Magazine.

"I know that there have been people who walked into a casino and bet a million dollars, but not on basketball. It was always the Super Bowl," Benjamin Lee Eckstein of AmericasLine.com, a nationally-syndicated odds column, told the Daily News. Furthermore, Eckstein noted that Mayweather's hefty bet would have only yielded him a $600,000 profit.

Mayweather has been known to tweet betting slips. As Grantland.com reports, between August 2010 and February 2012, Mayweather tweeted photographs of 46 betting slips, which totaled $3,890,833 worth of bets. Of those slips, every one of them was a winner, which earned the boxer a profit of $3,938,722.

Asked at the time about his losing slips in February 2011, Mayweather tweeted, "Why would I ever show a losing ticket when I'm 41-0."

The 41-0 was a reference to his professional boxing record at the time. Mayweather presently boasts a 44-0 undefeated record as a pro boxer since his first pro fight in October 1996.
